CROSS-BOND FOR RAILS.

SPECIFICATION forming part of Letters Patent No. 698,251, dated April22, 1902.

Application filed January 30, 1902. Serial No. 91,849. (No model.)

T0 ctZZ whom it may concern.-

Be it known that I, GEORGE B. BLANOHARD, of Tacoma, county of Pierce,State of Washington, have invented an Improvement in Cross-Bonds forRails, of which the following description, in connection with theaccompanying drawings,'is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object the production of a cross-bond forrails which may be firmly secured to the rails and a good connectioninsured for the passage of the current.

The invention consists in a cross-wire having at each end alaterally-projecting strip, the extremity of which is adapted to be at-In the preferred embodiment of my invention this laterally-projectingstripconsists of a laminated strip composed of a plurality ofsuperimposed layers of copper or other material, and said laminatedstrips are soldered or otherwise secured to the ends of the cross- Wireand are provided at their extremities with fiat feet adapted to besoldered to the rails and also provided with extensible portionsintermediate their ends. My invention, however, includes within itsscope any other form or construction of laterally-projecting stripsattached to the ends of a cross-wire adapted to be attached to orconnected with the rails.

Figure 1 shows in plan view a cross-bond embodying this invention, andFig. 2 is an enlarged cross-sectional detail of one of thelaterally-projecting strips.

or represents the cross-wire, which is herein shown as circular incross-section, yet it may be of any other shape in cross-section.

The cross-wire a, which is made of any suitable length, is herein shownas a single piece of metal, yet so far as my invention is concerned anyother form or construction of strip may be employed adapted to serve asa crosswire. The strip projects laterally from each end of thecross-wire for the attachment of said cross-wire'to the rails, and, asherein shown, this strip is made as a laminated strip comprising aplurality of layers 1), soldered together at each end and unattachedalong their intermediate portions. The intermediate portion of thelaminated strip is bent or formed to provide an extensible portion, yetthis is not absolutely necessary. One end of the laminated strip iswound around the cross-wire, as at b, and is secured thereto by solder,yet it may be otherwise attached to said cross-wire. The opposite end ofthe laminated strip is formed as a fiat foot 6 and on the bottom thereofa thick layer of sheet-solder is attached, preferably at one end only.

This bond will be attached to the rails by first cleaning a spot on therail, then heating the rail, and then applying the bond and hold- I ingits flat foot bearing the thick layer of S01- der firmly in contacttherewith.

What I do claim, and desire to secure by Letters Patent, is

1. Across-bond consisting of a cross-Wire and a laterally proj ectingstrip attached thereto at both ends, substantially as described.

2. A cross-bond consisting of a cross-wire,

and a laminated strip attached thereto at both 1 ends, substantially asdescribed.

3. A cross-bondconsisting of a cross-wire having a laminated stripattached thereto at both ends and projecting laterally therefrom,
